zfred09 Posted January 25, 2007 Share Posted January 25, 2007 My goal of this is to say if $var isnt set then set it, but when I goto the page nothing shows up, but then if I refresh the page the string will show up. It's as if when I first load the page it just doesn't read the isset part or something.[code]if(!isset($var)){$_SESSION['var']="23213123";} echo "$var";[/code] Link to comment https://forums.phpfreaks.com/topic/35702-isset-function-not-working/ Share on other sites More sharing options...
zq29 Posted January 25, 2007 Share Posted January 25, 2007 I don't have an answer to your question, but you should [i]really[/i] be scripting with register_globals switched off in your php.ini Link to comment https://forums.phpfreaks.com/topic/35702-isset-function-not-working/#findComment-169166 Share on other sites More sharing options...
Jessica Posted January 25, 2007 Share Posted January 25, 2007 if(!isset($var)){$_SESSION['var']="23213123";} echo "$var";When you first load the page var ISN'T set. $_SESSION['var'] is, but $var is not.Change to:if(!isset($var)){ $var = '23213123'; $_SESSION['var']=$var;} echo $var;And it will echo every time.ps: don't put quotes around varables that don't need them.

Jessica Posted January 25, 2007 Share Posted January 25, 2007 Ah good point. If this is the entire page, you're right, RG is on. If there's more code, perhaps $var = $_SESSION['var']; earlier on?I dunno, either way. You're right it should be off. I think the code I posted will fix the immediate problem.

zfred09 Posted January 25, 2007 Author Share Posted January 25, 2007 That is at the very top of the page and isn't defined later on. And what is the benefit of register globals being off? Security?

trq Posted January 25, 2007 Share Posted January 25, 2007 Yes, security. Itys also allot easier to keep track of variables when there aren't mysterious globals floating around.
